Celine Dion super-fan Richard Dunn has met his idol. Dunn became an internet sensation several weeks ago when he posted a video of himself singing Dion's hit "All by Myself" while stuck at McCarran Airport.

"What do you do when you're stuck at the Las Vegas Airport overnight?" reads a message at the beginning of the video. "Shoot a music video on your iPhone. That's what." Dunn then lip-synchs the entire ballad while roaming throughout the completely empty airport.

Dunn's video even caught the attention of Miss Dion herself. The 46-year-old singer reached out to Dunn in a YouTube video last month.

"Hi, Richard! I have to say that the video was hilarious and very touching. I loved it," she says in the clip. "Next time, you know, you're stuck all by yourself at Las Vegas airport for hours and hours, please be my guest at my show. By the way, Richard, you're more than welcome to use my bathroom. So I hope to see you soon!"

Dunn and his family attended Dion's Fourth of July show in Vegas and got to pose with her during a special backstage meet and greet.

After the get-together, Dunn told the Las Vegas Sun, "This is a once-in-a-lifetime memory I never thought would happen but will last forever."
